Calcium Phosphate - Research Article from Chemical Compounds

Overview

The three forms of calcium phosphate (KAL-see-um FOSS-fate) all occur as tasteless, odorless, colorless to white crystalline or powdery solids.

Dibasic calcium phosphate, CaHPO4, is also called calcium monohydrogen phosphate, dicalcium orthophosphate, or secondary calcium phosphate. It is usually found in the form of hydrate, such as CaHPO4·2H2O. It does not melt, instead decomposing when heated to 109°C (228°F).

Monobasic calcium phosphate, Ca(H2PO4)2, is also known as calcium hypophosphite, calcium biphosphate, acid calcium phosphate, monocalcium orthophosphate, and primary calcium phosphate. It usually exists in the form of the hydrate Ca(H2PO4)2·H2O. It decomposes when heated to 200°C (400°F)
